Abstract
Description
- 1. Field of the Invention
- The present invention relates to a suction valve assembly opened and closed by a fluid pressure, and more particularly, to a suction valve assembly of a compressor that is capable of preventing generation of a dead volume inside a compressor.
- 2. Description of the Background Art
- In general, a suction valve assembly is installed between a compression chamber in which a fluid is compressed in a compressor or the like and a suction passage which sucks the fluid, so that, when the fluid is sucked, the suction valve assembly is opened by an inertia and supplies the fluid introduced through the suction passage to the compression chamber, and when the fluid is compressed, the suction valve assembly prevents the fluid being compressed in the compression chamber from flowing backward to the suction passage.
- FIG. 1 is a partial sectional view of a compressor employing the suction valve assembly in accordance with a conventional art, and FIG. 2 is a view showing an operational state of the compressor employing the suction valve assembly in accordance with the conventional art.
- The conventional compressor includes a cylinder fixedly disposed at a case (not shown) and forming a
compression chamber 102, apiston 106 inserted into thecylinder 104 to be linearly and reciprocally movable to compress a fluid, and a suction valve assembly disposed at a front side of thepiston 106 and opening and closing the fluid being sucked. - The
piston 106 includes asuction passage 108 formed at the center thereof in a longitudinal direction to suck a fluid. Asupport portion 112 is formed at a front side of thepiston 106, having asuction hole 110 to supply the fluid introduced into thesuction passage 108 to thecompression chamber 102. Avalve seat 114 is formed at a front side of thesupport portion 112. - The suction valve assembly consists of a
valve body 116 tightly adhered to thevalve seat 114 and opened and closed, and aconnection bolt 118 connected between thevalve body 116 and thesupport portion 112 in order to prevent the valve body from releasing from thevalve seat 114. - The
valve body 116 is formed tapered with a certain angle at its outer circumferential surface and contacted to thevalve seat 114, athrough hole 120 is formed at the center thereof that theconnection bolt 118 penetrates, and aguide groove 124 is formed with a diameter extended from the throughhole 120 so that abolt head 126 of theconnection bolt 118 can be inserted to be linearly movable. - The
connection bolt 118 passes the throughhole 120 and bolt-engaged with thesupport portion 112, and thebolt head 126 of theconnection bolt 118 is inserted into and linearly movable in theguide groove 124. - That is, when the
valve body 116 is linearly moved and released from thevalve seat 114, the bolt head of theconnection bolt 118 is hooked at the inner side of theguide groove 124, so as to prevent thevalve body 116 from releasing outwardly from thepiston 106. - In the conventional suction valve assembly of a compressor constructed as described above, when the
piston 106 is retreated by the operation of the driving unit (not shown) of the compressor to supply a fluid into thecompression chamber 102, thevalve body 116 is released from thevalve seat 114 owing to the pressure of the fluid, so that the fluid introduced into thesuction hole 110 of the piston is supplied to thecompression chamber 102. - In this state, when the
piston 106 is advanced for a compression operation of the fluid, thevalve body 116 is tightly contacted to the valve seat 115 owing to the pressure of the fluid, whereby the fluid of thecompression chamber 102 is prevented from flowing backward to the suction side. - However, the conventional suction valve assembly of a compressor has the following problems. That is, as described above, the guide groove with a certain volume is formed in the valve body so that the bolt head supporting the linear movement of the valve body can be linearly moved. In this respect, since the guide groove forms a portion of the compression chamber, the fluid of the compression chamber is introduced into the guide groove, when the fluid is compressed, to create a dead volume, which results in degradation of a compression efficiency.
- In addition, when the fluid is compressed, in order to prevent the fluid from leaking into a gap between the through hole formed at the valve body and the connection bolt, a precision processing is required for sealing the parts. This causes a problem of increase in a fabrication cost.
- Therefore, an object of the present invention is to provide a suction valve assembly of a compressor in which a guide groove inside a compression chamber is removed to prevent generation of a dead volume, thereby improving an efficiency of a compressor.
- Another object of the present invention is to provide a suction valve assembly of a compressor in which a portion of a valve from which a fluid is leaked is removed to thereby reduce a fabrication cost and prevent degradation of a compression efficiency due to fluid leakage as a precision processing of a part for preventing the fluid leakage is not necessary.
- To achieve these and other advantages and in accordance with the purpose of the present invention, as embodied and broadly described herein, there is provided a suction valve assembly of a compressor including: a piston disposed movable in a cylinder forming a compression chamber, having a suction passage for sucking a fluid and a valve seat formed at a front side thereof; a valve body contacted to the valve seat to open and close the fluid, of which a front side making a portion of the compression chamber is formed hermetical; a support rod inserted into a rear portion of the valve body and fixed at one side of the piston and supporting the valve body to be moved in a certain range; and a release preventing unit formed between the valve body and the support rod to prevent the valve body from releasing from the support rod.
- In the suction valve assembly of a compressor of the present invention, the valve body of the suction valve assembly is formed tapered at its outer circumferential surface with a certain angle so as to be tightly adhered to the valve seat, and has a through hole formed at a rear side, into which the support rod is inserted, and a space part extended from the through hole and having a diameter larger than that of the through hole.
- In the suction valve assembly of a compressor of the present invention, the support rod is formed integrally with the support portion formed at a front side of the piston.
- In the suction valve assembly of a compressor of the present invention, the release preventing unit of the suction valve assembly includes a female screw formed at an inner circumferential face of an insertion groove of a valve body and a male screw formed at an end portion of the support rod and engaged with the female screw.
- In the suction valve assembly of a compressor of the present invention, the space part of the valve body is formed with a certain gap so that an inner side of the space part and an upper face of the male screw of the support rod are not in contact with each other when the valve body is tightly adhered to the valve seat.
- The foregoing and other objects, features, aspects and advantages of the present invention will become more apparent from the following detailed description of the present invention when taken in conjunction with the accompanying drawings.

- Reference will now be made in detail to the preferred embodiments of the present invention, examples of which are illustrated in the accompanying drawings.
- There may exist a plurality of embodiments of a suction valve of a compressor in accordance with the present invention, of which the most preferred one will now be described.
- FIG. 4 is a partial sectional view of a compressor adopting a suction valve assembly in accordance with the present invention, and FIG. 5 is an enlarged view of a portion ‘B’ of FIG. 4.
- A compressor of the present invention includes a
cylinder 4 fixed at a compressor case (not shown) and forming acompression chamber 2, apiston 6 disposed movable linearly and reciprocally inside the cylinder 5 to compress a fluid and forming asuction passage 8, and a suction valve assembly installed at a front side of thepiston 6 and preventing a fluid from flowing backward from thecompression chamber 2 to thesuction passage 8. - The
piston 6 is moved hermetically and reciprocally inside thecylinder 4, in which asuction passage 8 for sucking a fluid is formed in a longitudinal direction. Asupport portion 12, where a plurality ofsuction holes 10 through which the fluid sucked into thesuction passage 8 is supplied to thecompression chamber 8 are formed, is installed at a front side of thepiston 6. Avalve seat 14 is formed in a shape of hole tapered with a certain angle at a front side of thesupport portion 12. - The suction valve assembly consists of a
valve body 16 contacted to thevalve seat 14 to open and close the fluid; and asupport rod 18 connected between thevalve body 16 and thesupport portion 12 and supporting thevalve body 16 so as to be moved in a certain range. - The
valve body 16 is formed tapered in its outer circumferential surface so as to be tightly adhered to an inner circumferential surface of thevalve seat 14, a front side of thevalve body 16 forming the compression chamber together with the inner circumferential surface of thecylinder 4 is formed plane so as to prevent creation of a dead volume inside thecompression chamber 2, a throughhole 20 is formed at a rear side of thevalve body 16, into which thesupport rod 18 passes, and aspace part 22 is formed at the inner side of the throughhole 20 in which thesupport rod 18 is moved in a certain range after being inserted. - One side of the
support rod 18 is fixed at thesupport portion 12, and a release preventing unit is formed at the other end portion to prevent thesupport rod 18 from releasing from thespace part 22 after being inserted into the throughhole 20 of the valve body. - The
support rod 18 is preferred to be molded integrally with thesupport portion 12 in a manner of being protruded forwardly of thesupport portion 12. - Otherwise, the support portion and the support rod may be fabricated separately and then mutually engaged with each other.
- As for the release preventing unit, in order to prevent the
support rod 18 from being released after being inserted into the throughhole 20 of thevalve body 16, amale screw 24 with a diameter larger than that of thesupport rod 18 is formed at an end portion of thesupport rod 18 and afemale screw 26 to be spirally coupled with themale screw 24 is formed at an inner circumferential surface of thethrough hole 20. - That is, after the
male screw 24 of thesupport rod 18 is spirally engaged with thefemale screw 26, themale screw 24 of thesupport rod 18 is movably positioned inside thespace part 22 of the valve body. Then, when thevalve body 16 is linearly moved, themale screw 24 hooked at the inside of thespace part 22 to thereby prevent release of thevalve body 16. - Besides the structure of the release preventing unit constructed with the female screw and the male screw, any structure can be applied to the release preventing unit as long as it prevents the support rod from being released after being inserted into the
space part 22. - As shown in FIG. 5, referring to the
space part 22 of the valve seat, when thevalve body 16 is tightly adhered to thevalve seat 14, there is a gap between thevalve seat 14 and the front side of themale screw 24, so that when thevalve body 16 is moved, the inner circumferential surface of thespace part 22 and themale screw 24 are not in contact with each other, to thereby prevent occurrence of a noise and vibration. - The operation of the suction valve assembly of a compressor of the present invention constructed as described above will now be explained.
- FIG. 6 is a view showing a use state of a compressor adopting the suction valve assembly in accordance with the present invention, and FIG. 7 is an enlarged view of a portion ‘C’ of FIG. 6.
- First, in case that a fluid of the
suction passage 8 is supplied to thecompression chamber 2, when thepiston 6 is retreated according to an operation of a driving unit (not shown), thevalve body 16 is released from thevalve seat 14 due to an inertia according to the fluid flowing and the movement of the piston, so that the fluid introduced into thesuction passage 8 is supplied to thecompression chamber 2 through thesuction hole 10. - At this time, the
male screw 24 formed at the end portion of thesupport rod 18 is hooked in thespace part 22 of thevalve body 16, whereby thevalve body 14 is prevented from being released from thepiston 6. - In this state, when the
piston 6 is advanced to compress the fluid, thevalve body 16 is tightly adhered to thevalve seat 14 owing to the inertia according to the advancing of thepiston 6 and the pressure of the fluid filled in thecompression chamber 2. Thus, the fluid of thecompression chamber 2 can be prevented from flowing backward to the suction side. - In this respect, since the upper surface of the
valve body 16, which makes a portion of thecompression chamber 2, is formed plane, a dead volume can not be created inside thecompression chamber 2, and thus, a compression efficiency of the fluid is increased. - At this time, when the
valve body 16 and thevalve seat 14 are tightly adhered to each other, the gap is maintained between the upper surface of themale screw 24 of thesupport rod 18 and the inner wall of thespace part 22, so that a noise and vibration according to the contact between themale screw 24 and the inner circumferential face of thespace part 22 when thevalve body 16 is opened and closed can be prevented, and a tight adherence between thevalve body 16 and thevalve seat 14 can be maintained. - As so far described, the suction valve assembly of a compressor in accordance with the present invention has the following advantages.
- That is, the upper surface, making the compression chamber of the valve body of the suction valve assembly is plane not to allow a dead volume to be created, so that a compression efficiency of the fluid can be improved.
- In addition, since no fluid is leaked, a precision processing of parts for sealing a fluid is not necessary. Thus, a fabrication cost can be reduced and degradation of a compression efficiency due to a fluid leakage can be prevented.
- As the present invention may be embodied in several forms without departing from the spirit or essential characteristics thereof, it should also be understood that the above-described embodiments are not limited by any of the details of the foregoing description, unless otherwise specified, but rather should be construed broadly within its spirit and scope as defined in the appended claims, and therefore all changes and modifications that fall within the meets and bounds of the claims, or equivalence of such metes and bounds are therefore intended to be embraced by the appended claims.
